Shadow Pressure refers to the action that requires one defender to "Shadow" at a distance approximately 8 feet to 10 feet behind, the teammate who is pressuring the ball handler. It is the basis of SOS full court disruptions. The player in the "Shadow" position, in order to keep the ball handler off balance and confused, has three options (trap, hold or jump switch). The Shadow position is interchangeable dependent of which offensive player is the inbounds passer.
Shadow Trap Option
On made shots, the player defending the inbound passer sprint releases to a "Shadow" support position 8' to 10' directly behind X1 and X2 ready to deny any over the top pass to O1 or O2. Once ball is inbounded the Shadow X5 then shadows the ball handler supporting the on ball defender X1 to apply extreme defensive pressure.
Phase 1: Shadow Action.
When the ball is inbounded to O1, X1 after initially assuming a SNUGGLE pass denial position on O1, moves to an ON position and pushes O1 to side checkpoint. Defender X2 rotates from a SNUGGLE denial position on O2 to a high Helpside "I" position. X3 maintains a SNUGGLE pass denial position on O3. X4 rotates to a low Helpside "I" position. "Shadow" X5 shadows ball handler O1 moving into position to trap O1 with X1 on near sideline checkpoint. If ball is inbounded to O2, X2 assumes the ON position with X5 assuming a "Shadow" position behind X2. X4 maintains a pass denial SNUGGLE position on O4, and X1 and X3 rotate into Helpside "I" positions.
NOTE: when any time the shadow player X5 is unable to get into proper position, Shadow pressure is off and basic half court oriented SOS rules apply. Also, on any deep outlet or outlet into the middle of the floor, Shadow pressure is not feasible, and basic transition pressure defense is in effect.
Phase 2: Double Team (Trap).
X1 and "Shadow" X5 lock up and trap dribbler O1 on near sideline checkpoint. X2, X3 and X4 form a Helpside Triangle "I." In the Shadow position, X5 has options of trapping the ball handler O1 with X1 or faking the trap (Hold) according to read or coach's decision. X4 assumes a SNUGGLE pass denial position on O4 while X2 and X3 assume Helpside "I" positions.
Phase 3: Matching Up
When O1 passes the ball out of the trap to O2, X2 closes out and pushes O2 to sideline checkpoint. X4 closes out to O4 and assumes a SNUGGLE pass denial position. X5 sprint releases to the basket and guards O5. X3 drops into a low Helpside "I" position, and X1 takes a strong pass denial position against O1, preventing any return pass that would allow O1 to initiate the set offense. If O2 passes ahead to O4, X4 assumes a SET position and pushes O4 to corner or baseline checkpoint. X5 FRONTS O5 in low post area. X2 creates "Box Pressure" by assuming a Snuggle pass denial position on O2. X1 and X3 take Helpside "I" positions.
Caution: It is extremely important that all close outs and rotations take place as the ball leaves the passer's hands.
Phase 4: Secondary Baseline Trap
Anytime the ball is advanced on dribble or pass to an area below the free throw line extended, SOS Base Go I or at the coach's discretion Base Go Red rules are in effect. Often times teams are caught off balance, after advancing the ball through initial full court pressure, since they do not expect to encounter a second trap when they run their set offense.
